LEED-Green-Associate Exam Dumps - USGBC Leadership in Energy and Environmental Design (LEED) Questions and Answers

The Location and Transportation (LT) category addresses the location and accessibility of a project site, as well as its impacts on transportation, land use, and community connectivity. One of the credits in this category is LT Credit: Surrounding Density and Diverse Uses, which rewards projects that are located in areas with high density and a variety of land uses, such as retail, residential, and civic facilities. This can reduce vehicle miles traveled, greenhouse gas emissions, and infrastructure costs, as well as promote walkability, livability, and social interaction. A new project that is built adjacent to a park with a trail leading to an urban business district qualifies for this credit by providing pedestrian access to diverse uses within a 1/2 mi. (0.80 km) walking distance1 . References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide

The U.S. Green Building Council (USGBC) administers the LEED rating systems development. The LEED rating systems are frameworks that provide guidance and criteria for designing, constructing, operating, and maintaining green buildings. The USGBC is responsible for developing, maintaining, and updating the LEED rating systems through a consensus-based process that involves various stakeholders, such as technical experts, industry leaders, government representatives, and public comments. The LEED Green Associate Candidate Handbook states that “USGBC is committed to transforming the way our buildings are designed, constructed and operated through LEED” [1, p. 7]. References: LEED Green Associate Candidate Handbook, [LEED Rating Systems | U.S. Green Building Council]

The Sustainable Sites (SS) category addresses the site selection, design, construction, and operation of a project, as well as its impacts on the natural and built environment. One of the goals of this category is to reduce light pollution and discourage the development of previously undeveloped land. Light pollution is the excessive or inappropriate use of artificial lighting that can have adverse effects on human health, wildlife, ecosystems, and astronomy. Previously undeveloped land is land that has not been graded, cleared, or built upon prior to the current project and remains in a natural state. Developing previously undeveloped land can result in habitat loss, soil erosion, stormwater runoff, and increased infrastructure costs13. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide3

The scope of the LEED impact category component Protect Human Health from Direct Exposure to Negative Health Impacts is building occupants and design and construction crew during the construction phase and use phase of the building cycle, within the project boundary and its immediate surroundings. This component aims to reduce the exposure of people to harmful substances or conditions that may affect their health and well-being. This includes indoor air quality, thermal comfort, lighting quality, noise levels, water quality, and safety hazards. The component covers both the construction phase and the use phase of the building cycle, as both stages can pose potential health risks to people involved or affected by the project. The component also considers both the project boundary and its immediate surroundings, as some health impacts may extend beyond the site itself. References: LEED v4 BD+C Reference Guide, Introduction, page 9

The Forest Stewardship Council (FSC) is a third-party verification organization that certifies forest products that are sourced from responsibly managed forests that meet environmental, social, and economic standards12. FSC-certified wood products are considered environmentally preferable products under the LEED v4 Materials and Resources category, as they reduce the negative impacts of deforestation, habitat loss, and biodiversity loss34.

Light-colored paving and cool roofs refer to materials with higher emissivity and higher albedo. Emissivity is the ability of a material to emit heat that it absorbs, while albedo is a measure of how much light that hits a surface is reflected without being absorbed. Materials with high emissivity can help reduce heat islands by releasing more of the heat they absorb, while those with high albedo can reflect more sunlight and thus stay cooler. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

ASHRAE 189.1 is a standard for the design of high-performance green buildings that covers various aspects of sustainability, energy efficiency, water efficiency, indoor environmental quality, and more. It is an alternate compliance path for the IGCC, which is a model code that contains minimum requirements for green building design and construction. In jurisdictions that adopt the IGCC, a builder has the option to design and construct a building in accordance with the provisions of ASHRAE 189.1 rather than those of the IGCC123.

A closed system is a type of approach that promotes the conservation of materials and resources by linking elements in order to form relationships with their function1. A closed system is one that does not exchange matter or energy with its surroundings, and therefore minimizes waste and maximizes efficiency2. A closed system aims to achieve a circular economy, where resources are reused, recycled, or recovered, rather than disposed of3. A closed system can also enhance resource productivity, reduce environmental impacts, and foster innovation4.

The Integrative Process Credit in LEED v4 requires the project team to implement an integrative process that enables them to discover unique opportunities for enhancing project performance and environmental benefits1. The project team should identify and use opportunities to achieve synergies across disciplines and building systems2.

The footprint of a building is the area of ground that it covers, defined by its perimeter. It’s essentially the shape that results when you trace around the outer walls of a building plan. This term is used in architecture and urban planning to describe the space that a building occupies on a site. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
